Shrimp culture industry (approximately 80 billion Baht value) is greatly affected byloss (as much as 25%) due to viral diseases. Raising protective immunity in cultured shrimpis a strategic research to find a means to prevent the economic loss of the shrimp industry.However, the protective immunity in shrimp is different from that in human and is largelyunknown. A new approach to raise protective immunity in shrimp is desirable. A method toprevent pathogenic virus to replicate inside shrimp cells is a promising alternative to protectshrimps from viral diseases. Gene silencing by small interference RNA (siRNA) has beendemonstrated to inhibit viral replication in a few invertebrate cells such as those ofDrosophila. Thus, it is envisaged that if gene silencing by siRNA was functional in shrimpcells it should lead to a devise of siRNA which could inactivate the viral mRNA andconsequently inhibit the viral replication. A failure of the viruses to replicate in shrimp shouldgive rise to a new means of protective immunity. Specific siRNA may be designed tosynthesize inside shrimp cells. One method is to use a “friendly virus” of shrimp as a vectorto deliver siRNA. This engineered viral vector may be further developed to create a new typeof vaccine in shrimp and other animals.
